Subject: [xsl] using keys as cross-reference From: Xiaocun Xu <xiaocunxu@xxxxxxxxx> Date: Sun, 20 Jan 2002 07:38:08 -0800 (PST) |
Hi, I am interested to implement cross-reference using keys (suggested by Jeni as well as documented in the XSLT Programmer Reference 2nd Ed. on p.501-3). My situation is I have more readable headers in Excel (i.e. *Organization Unique ID)that needs to be translated into DTD attribute names (i.e. OrganizationCode). I intend to put the name-value mapping in a separate XML, which I want to use keys to retrieve the translation. I see two ways to accomplish this: 1. translates all the headers at the beginning of the stylesheet into global variables. This way, I do not have to write user defined extensions. The drawback to this I lose extensibility, it will be difficult when I also wish to translate values other than the headers. 2. user defined extension to translate between name and value on demand. Are there other more effective solutions? Regarding solution #2 user defined extension, how to pass the key into the extension since <xsl:key> has to be top-level element? With example on XSLT Programmer Reference 2nd Ed. on p.502, <xsl:key name="biog" match="author" use="@name"/> In my extension function, can I directly use: key('biog', $name)? Much thanks, Xiaocun __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
